Description

TECHNICAL FIELD

The present invention relates to the field of communications technologies, and in particular, to a control method and apparatus for a wireless fidelity (wireless fidelity, wifi) device, and a terminal.

BACKGROUND

When a terminal does not use a wifi function, a wifi device for starting a wifi connection in the terminal is in a standby state, and therefore certain power is still consumed. For example, test data in a certain mobile phone indicates that if no wifi access point identifier has been stored, a current is about 5 milliamps when the screen of the mobile phone is turned off, while if a wifi access point identifier has been stored, a current is about 10 milliamps when the screen of the mobile phone is turned off.
If a wifi device in a terminal is turned off immediately after the terminal is disconnected from a wifi access point, when re-entering an area covered by the wifi access point, the wifi device cannot be automatically connected to the wifi access point.
The inventor of the present invention finds that, a common problem for a wifi device is that, after leaving an area covered by a wifi access point, the wifi device enters a standby state, thereby causing an additional current consumption of 5-10mA, and if the wifi device is turned off, when re-entering the area covered by the wifi access point, the wifi device cannot be automatically turned on.

The embodiments of the present invention further provide a corresponding apparatus and terminal, which are described separately in detail in the following.
The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the embodiments to be described are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
Referring to FIG. 1, an embodiment of a control method for a wireless fidelity (wireless fidelity, wifi) device in a terminal provided in the embodiments of the present invention includes:

101: Acquire a first location of the terminal at a first moment, a second location of the terminal at a second moment, and coverage of each of wifi access points corresponding to each of all wifi access point identifiers stored in the terminal, where the first moment is earlier than the second moment.

For wireless fidelity (wireless fidelity, wifi), a network is connected through a radio wave, generally a wireless router is used, and a network can always be connected in a wifi connection manner within an effective area covered by a radio wave of the wireless router.
The wifi device is a wifi module in the terminal, where the wifi module establishes a connection to a wifi access point.
The wifi access point may be a terminal device such as a wireless router, and a computer or a mobile phone with a wifi function.
The terminal in the embodiment of the present invention may be a device such as a mobile phone, a personal digital assistant (personal digital assistant, PDA), and a notebook computer.
After establishing a connection to a wifi access point for the first time, the terminal stores an identifier of the wifi access point, such as an identifier of a wireless router.
Each wifi access point has coverage. Definitely, coverage of wifi access points corresponding to wifi access point identifiers stored in the terminal may all overlap, or partially overlap, or not overlap at all.
In a moving process, the terminal may move out of coverage of a wifi access point from the coverage of the wifi access point. If the terminal moves out of the coverage of the wifi access point, a wifi connection is disconnected, and if the wifi is still in an on-state, power is consumed.
In the moving process of the terminal, location information of the terminal may be acquired continuously, where location information of a location where the terminal is located may be an identifier of a serving cell where the terminal is located, and preferably, is location information of accurate longitude and latitude obtained through positioning of a global positioning system (Global Positioning System, GPS).
Each wifi access point has a unique identifier, and coverage of a wifi access point may be set before the wifi access point leaves the factory, for example, an identifier of a wireless router corresponds to coverage of the wireless router.
102: Trigger turning-off of the wifi device when it is determined that the terminal is located within coverage of at least one wifi access point among the wifi access points at the first moment, and is located outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the second moment.
In the embodiment of the present invention, the determining whether the terminal is located within the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the first moment and whether the terminal is located within the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the second moment may be determining whether a location of the terminal at the first moment and a location of the terminal at the second moment are within or outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers.
For example, it is assumed that the terminal stores 5 wifi access point identifiers, which are wifi1, wifi2, wifi3, wifi4, and wifi5, and coverage of a wifi access point corresponding to each of the wifi access point identifiers has been determined. It is assumed that coverage of a wifi access point corresponding to wifi1 and coverage of a wifi access point corresponding to wifi2 partially overlap, and coverage of a wifi access point corresponding to each of wifi3, wifi4, and wifi5 does not overlap with coverage of the other 4 wifi access points, and when the terminal begins to move in the coverage of the wifi access point corresponding to wifi1, first location information at a first moment and second location information at a second moment are acquired. It is assumed that a location corresponding to the first location information is within the coverage of the wifi access point corresponding to wifi1, and if a location corresponding to the second location information is within the coverage of the wifi access point corresponding to wifi2, a handover between the wifi access points occurs; and if the location corresponding to the second location information is not within the coverage of the wifi access points corresponding to wifi1, wifi2, wifi3, wifi4, and wifi5, the turning-off of the wifi device can be triggered, so as to reduce power consumption of the wifi device.
103: Trigger turning-on of the wifi device when it is determined that the terminal is located outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the first moment, and is located within coverage of at least one wifi access point among the wifi access points at the second moment.
In the embodiment of the present invention, the determining whether the terminal is located within the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the first moment and whether the terminal is located within the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the second moment may be determining whether a location of the terminal at the first moment and a location of the terminal at the second moment are within or outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers.
For example, it is assumed that the terminal stores 5 wifi access point identifiers, which are wifi1, wifi2, wifi3, wifi4, and wifi5, and coverage of a wifi access point corresponding to each of the wifi access point identifiers has been determined. It is assumed that coverage of a wifi access point corresponding to wifi1 and coverage of a wifi access point corresponding to wifi2 partially overlap, and coverage of a wifi access point corresponding to each of wifi3, wifi4, and wifi5 does not overlap with coverage of the other 4 wifi access points, and when the terminal begins to move in the coverage of the wifi access point corresponding to wifi1, first location information at a first moment and second location information at a second moment are acquired. It is assumed that a location corresponding to the first location information is outside the coverage of the wifi access points corresponding to wifi1, wifi2, wifi3, wifi4, and wifi5, and a location corresponding to the second location information is within the coverage of the wifi access point corresponding to wifi1, and the turning-on of the wifi device can be triggered.
In the embodiment of the present invention, first location information of the terminal at a first moment, second location information of the terminal at a second moment, and coverage of each of wifi access points corresponding to each of all wifi access point identifiers stored in the terminal are acquired, where the first moment is earlier than the second moment; turning-off of the wifi device is triggered when it is determined that the terminal is located within coverage of at least one wifi access point among the wifi access points at the first moment, and is located outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the second moment; and turning-on of the wifi device is triggered when it is determined that the terminal is located outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the first moment, and is located within coverage of at least one wifi access point among the wifi access points at the second moment. Compared with the prior art in which a wifi device in a standby state wastes power, and after the wifi device is turned off, the wifi device cannot be automatically turned on, with the control method for a wifi device in a terminal provided in the embodiment of the present invention, turning-off or turning-on of the wifi device in the terminal can be triggered according to a location of the terminal in a moving process, so that power of the terminal is saved, and furthermore, the wifi device does not need to be turned on manually by a user.
Optionally, based on the embodiment corresponding to FIG. 1, in another embodiment of the control method for a wifi device in a terminal provided in the embodiments of the present invention, the step of triggering turning-off of the wifi device when it is determined that the terminal is located within coverage of at least one wifi access point among the wifi access points at the first moment, and is located outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the second moment may specifically include:

In the embodiment of the present invention, whether the location corresponding to the first location information of the terminal and the location corresponding to the second location information are within or outside the coverage of the wifi access points corresponding to the wifi access point identifiers stored in the terminal may be determined in a GPS positioning manner.
For example, if coverage of a wifi access point corresponding to a wifi access point identifier stored in the terminal is the Shenzhen International Trading Building, and it is acquired that in a moving process of the terminal, a location corresponding to first location information at a first moment is in the hall of the International Trading Building, and a location corresponding to second location information at a second moment is outside the entrance of the International Trading Building, it can be determined that the terminal has moved outside the coverage of the wifi access point, and turning-off of the wifi device can be triggered.
Optionally, based on the embodiment corresponding to FIG. 1, in another embodiment of the control method for a wifi device in a terminal provided in the embodiments of the present invention, the step of triggering turning-on of the wifi device when it is determined that the terminal is located outside the coverage of each of the wifi access points corresponding to each of all the wifi access point identifiers at the first moment, and is located within coverage of at least one wifi access point among the wifi access points at the second moment may specifically include:

In the embodiment of the present invention, if it is determined, through positioning of a GPS, that the location corresponding to the first location information of the terminal at the first moment is outside the entrance of the Shenzhen International Trading Building, and the location corresponding to the second location information at the second moment is the hall of the Shenzhen International Trading Building, it can be determined that the terminal enters the coverage of the wifi access point, and turning-on of the wifi device of the terminal can be triggered.
Optionally, based on the embodiment corresponding to FIG. 1 and an optional embodiment corresponding to FIG. 1, in another embodiment of the control method for a wifi device in a terminal provided in the embodiments of the present invention, the control method may further include:

When the wifi device finds only one wifi access point, the wifi device may establish a wifi connection to the found wifi access point. If the wifi device finds several wifi access points, the wifi device may establish a wifi connection to one selected found wifi access point.
Optionally, based on the embodiment corresponding to FIG. 1 and an optional embodiment corresponding to FIG. 1, in another embodiment of the control method for a wifi device in a terminal provided in the embodiments of the present invention, after the step of turning on the wifi device, the control method may further include:

When the wifi device finds only one or multiple wifi access points, the wifi device may return identifiers of the found wifi access points to the control apparatus, so that the control apparatus can determine an identifier of a wifi access point to which a connection is established for the most times, and instruct the wifi device to establish a connection to the wifi access point to which the connection is established for the most times.
For ease of understanding, a process of the control method for a wifi device in a terminal provided in the embodiments of the present invention is described in detail in the following by using an application scenario as an example.

A terminal 20 acquires, in a GPS or another manner, that first location information of the moving terminal 20 at a first moment is 90 meters to the left of the origin, and second location information of the moving terminal 20 at a second moment is 101 meters to the left of the origin, so that it can be determined that the terminal 20 moves outside the coverage of the wifi access point 10, and the terminal 20 can trigger turning-off of a wifi device in the terminal 20.
